Bear bear is the one in green he's basically(as mr.stretchy has claimed)
Baby's second dad and mr.stretchys favorite toy around the factory bear bear has a scar on his lighter eye that caused him to lose sight in that eye he refuses to wear a eye patch even if the workers used to tell him he should

Bear bear is still romantically involved with mr.stretchy since they really liked each other when alive but couldn't really act on it since it was illegal now though seeing there's barely any workers alive they'll freely express emotions

(Bear bears design is based off bonzo bunny in chapter 2)
Baby

Babys the small doll her dads holding she's angry cause player almost stepped on her- again. She's normally very gentle and calm long as shes not out of her container too long shes a child the longer awake with no sleep the more grumpy she gets(based of the poppy theory)

Mr.stretchy is trying to call Elizabeth down he plans to probably hunt down player again and break a bone possibly

(Based of mommy long legs)

The next characters are the ringy ring's there the huggy wuggy based monsters you'll see red ringy ring/Scott and purple ringy ring/Vincent

They can remove there phone heads Scott doesn't like to though unlike Vincent who will physically just ✨yeet✨ his off  for kinda no reason but just to see better
